Age Calculator
Calculate age in years, months and days.
UNDERSTANDING THE TOOL
What age calculator does
Age calculations depend on calendar dates rather than a fixed number of 24-hour periods. This tool compares the selected birth date with the current date in the browser.
When it is useful
Calculate an age in years, months, and days from a date of birth. The page is designed for quick checks, preparation, and routine tasks where a focused utility is more convenient than doing the same steps manually.
Check the context. A calculator or converter can produce a mathematically correct result from the values supplied, but it cannot know whether those values, units, dates, or assumptions are appropriate for your particular situation.
PRACTICAL NOTES
Things to check
- Month lengths vary, so calendar-based age cannot always be reproduced by dividing a day count by 365.
- The browser date and time zone can affect edge cases around midnight.
- Do not use this utility as a legal determination of eligibility or age requirements.
LIMITS AND PRIVACY
What this page does not do
The calculation uses the browser date and time settings.
QuickTools does not ask you to create an account to use this tool. If you are working with confidential material, consider the security of your device, browser, network, and any destination where you later save or share the result.
